FORCE- PUMP.

SPECIFICATION forming part of Letters Patent No. 288,007, dated November6, 1883.

kbplication filedMarch 30, 1883. (No model.)

To all whom it may concern.-

Be it known that I, TIMOTHY CALVER, of

of Ohio, have invented a new and Improved Force-Pump, of which thefollowing is a full, clear, and exact description.

The object of my invention is to provide a new and improved force pumpwhich can throw a large quantity of water and is very simple in.construction.

Reference is to be "had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal elevation of my improved force-pump, partsbeing shown in section. Fig. 2 is a plan view of the same on the line a:a, Fig. 1. Fig. 3 is a front elevation of the upper part of the pump.

On a base-plate, A, .which rests on the bottom of the well, cistern,8tc., four horizontal pump-cylinders, B, are placed at right angles toeach other and in such a manner that the central axes of the twoopposite cylinders of each pair will form a continuous right line, thesaid two right lines crossing each at right an gles. The cylinders areopen at the outer ends and closed at the inner ends. A

Each cylinder contains a piston, F, attached. to the end of ahorizontal'pistonrod, G, passing through the inner closed end of itscylinder. The inner ends of the opposite piston rods are attached toopposite sides of a plate angles to the piston-rods, the slots J of thetwo plates or frames H crossing each other at right angles.

A vertical shaft, K, is journaled at its up ards, M, in the cover or topplate, N, of the well or cistern, and the lower end "of the shaft K isjournaled in the base-plate A, directly below the axes of the cylindersB. The shaft K also passes through a guide loop or ring, I, on the endof an arm, I, secured to the bottom of the cover N.

At its lower end the shaft K is provided with a crank, O, which passesthrough the slots J of the plates or frames H. bevelcog-wheel, Q,mounted on a transverse shaft, R, journaled in the standards M, providedwith a crankhandle, S.

The pump-barrel T, which is closed. at the is rotated, and the crank O,acting against theedges of the slots J, reciprocates the two pairs ofpiston-rods at right angles to each other. For each revolution of theshaft K each piston is moved backward and forward in its cylinder, andeach cylinder is filled and emptied,

and thus for each revolution of the shaft K the contents of the fourcylinders will be raised and discharged.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, with the single 'crank O of thedrive-shaft and the cylinders B, of two rods, G G, carrying a piston ateach end, arranged at right angles to each other and transverselyslotted in the middle, as shown, whereby only a single'crank is neededand pitmen for connecting the crank with the piston-rods are dispensedwith.

2. In a force-pump, the combination, with the cylinders B, arrangedopposite each other in pairs and at right angles to each other whichcylinders are open at the outer ends, of the pistons F, the piston-rodsG, of such length that the pistons can be moved out of the outer ends ofthe cylinders, and devices for. reciprocating the pistonssimultaneously, substantially as herein shown and described, and for thepurpose set forth.
